Image Optimization Plugins Comparison

In this section, we will compare EWWW Image Optimizer with other popular image optimization plugins to help you make an informed decision.

EWWW vs Smush

EWWW and Smush are both great image optimization plugins for WordPress. While EWWW provides automatic compression of uploaded images, Smush offers a bulk optimization feature that makes it easy to compress multiple images at once. However, EWWW’s lossless optimization may result in larger file sizes compared to Smush’s lossy compression.

EWWW vs ShortPixel

Both EWWW and ShortPixel are powerful image optimization plugins with their own strengths and weaknesses. ShortPixel provides advanced compression algorithms, delivering smaller file sizes without sacrificing quality. On the other hand, EWWW offers unlimited image optimization, while ShortPixel has a monthly limit on the number of optimized images.

EWWW vs Imagify

Imagify is another popular image optimization plugin that competes with EWWW. Imagify’s main advantage is its user-friendly interface, which makes it easy for beginners to set up and use. However, EWWW may offer more customization options and better compatibility with other plugins and themes.

EWWW vs Optimole

Optimole is a relatively new image optimization plugin that focuses on simplicity and speed. Its main feature is adaptive image resizing, which automatically resizes images based on the visitors’ screen sizes. This can save bandwidth and improve performance. EWWW, on the other hand, provides more comprehensive image optimization features and may be better suited for advanced users.


TinyPNG, also known as Compress JPEG & PNG Images, is a simple and effective plugin that focuses on lossy compression to achieve small file sizes without visible quality loss. In comparison, EWWW offers both lossless and lossy compression, giving users more flexibility in choosing the right balance between quality and file size.

EWWW vs reSmush.it

reSmush.it is a free image optimization plugin that uses its own server-side algorithm to compress images. This can lead to faster optimization times as it offloads the processing from your server. However, EWWW supports better integration with popular content delivery networks (CDNs) and offers more advanced optimization options.

EWWW vs Other Plugins

There are numerous other image optimization plugins available for WordPress, each with their own unique features. When comparing EWWW to these plugins, consider factors such as ease of use, compatibility with your existing setup, and the balance between quality and file size reduction.

Remember, choosing the right image optimization plugin for your WordPress site will depend on your specific needs, preferences, and goals. Explore each plugin’s features and find the best fit for your requirements.
